3General Description of the IVS
The Integrated Video-Assist System (IVS) for the ARRIFLEX
535B ergonomically integrates with a minimum of external
cabling a complete video assist system into the camera body.
It offers unsurpassed image quality combined with a state-of-
the-art inserter to add frame lines, time code, camera status
and text into the video image.
3.1 Main Features
•Integrated into the camera body:
Instead of a bulky add on, the video assist is an integral
part of the camera.
•High sensitivity:
A high speed lens with an aperture of 1: 1.4 and one of
the most sensitive CCD-chips available on the market
provide an excellent color video image in editing quality
even when the light is set for high speed film stock to
be pushed during processing.
•High resolution:
The design of the new IVS optics was based on the
535B’s viewfinder data and resulted in an image quality
which can not be attained by add-on solutions.
•Flicker-free:
An integrated digital frame store enables the video
camera to be synchronized to the film camera’s mirror
shutter and provides a flicker-free video image from
5-60 fps. The recording of the video image is synchro-
nized with the ideal position of the mirror shutter.
•Integrated frame line inserter:
Frame lines can be electronically added to the video
image. This ensures that the lines are visible even in
low contrast conditions. The area outside the frame
lines can be darkened electronically to emphasize the
important image area.
•Integrated IVS film counter:
In addition to the camera speed an independent IVS film
counter can be inserted into the camera status line to
support material logging.
General Description

12
•Integrated time code inserter:
It is possible to insert time code into the video image.
Thus, the video assist creates a reliable link to video
editing. The information on “3:2” pull-down, which
can be inserted as well, ensures the same reliability in
an NTSC environment.
•Integrated text inserter:
Additional text like take numbers or production names
can be added to the video image by sending characters
via a serial interface.
•Additional Y/C Outputs:
In addition to the usual composite output, the IVS
offers a Y/C output (S-VHS) for an even better video
image without annoying color artifacts, with or without
data inserted into the video image.
•On-Screen programming:
All functions which do not effect the image appearance
directly, such as gain control, can be conveniently pro-
grammed with an onscreen menu on the video monitor.
•Image compare function:
It is possible to store a particular image and compare
it against other images. This clearly shows the difference
between the images, e.g. during stop effect shots.
•Automatic and manual gain control:
The gain is controlled automatically to its best value
but can also be set manually.
•External synchronization input (Genlock):
The IVS has an external synchronization input to
enable multiple camera use.
•Indoor/Outdoor and automatic white balance:
White balance can be set to indoor with 3200 K,
outdoor with 5600 K and automatic adjustment.
•Mini monitor connector:
The IVS offers a connector for a 12 V LCD mini monitor.
Note: If neither time code is used nor data is sent via
the serial interface, it is possible to work without
the data cable ZV4.
Note: As the IVS is designed for an 80 : 20 beam splitter,
there is no need for the 50 : 50 beam splitter,
which is used for other color video assists.
General Description

3.2 System Components
The IVS consists of:
•Optic Silent and/or ............................ (K2.47298.0)
•Optic Academy ................................. (K2.47301.0)
•Video Electronic complete ......... (K2.47306.0 for PAL
or K2.47307.0 for NTSC)
The complete video electronic consists of four parts:
•CCD Optic Module
•Inserter/Antiflicker module
•RS cable............................................ (K4.47733.0)
•Data cable ZV4 ................................. (K4.47730.0)
3.2.1 Optic Silent
For a complete and working IVS, either the optic silent or
the optic academy has to be installed inside the CCD optic
module. These are easily interchangeable.
The optic silent forms an image on the CCD chip which is
based on the 35 mm silent format with a picture width of
24 mm. To check for important objects outside the image
recorded on film there is an additional area around the
format markings.
The lenses are especially designed and built for use with the
ARRIFLEX 535B to achieve the best image quality possible.
The aperture of 1:1.4 is particularly important for use as
video assist lenses: only a small portion of the light that passes
through the camera lens goes to the video chip. The lenses
are not designed as zoom lenses because it would be im-
possible to get the same image quality and speed.
All silent optics are marked with an S in the serial number,
e.g. S0040.
There is no difference between lenses for PAL and NTSC.
General Description

14
3.2.2 Optic Academy
For a complete and working IVS, either the optic silent or
the optic acacemy has to be installed inside the CCD optic
module. They are easily interchangeable.
The optic academy forms an image on the CCD chip based
on the 35mm academy format with a picture width of 22mm.
To check for important objects outside the image recorded
on film there is an additional area around the format markings.
The lenses are especially designed and built for the use with
the ARRIFLEX 535B to achieve the best image quality possible.
The aperture of 1:1.4 is particularly important for use as
video assist lenses: only a small portion of the light passes
goes through the camera lens goes to the video chip. The
lenses are not designed as zoom lenses because it would
be impossible to get the same image quality and speed.
All academy optics are marked with an N in the serial number,
e.g. N0040.
There is no difference between lenses for PAL and NTSC.
3.2.3 CCD Optic Module
The CCD optic module, which is mounted on the ARRI-
FLEX 535B’s viewfinder system, has to be equipped with
a video lens. This module contains the CCD chip and all
the necessary elements to center the video image on the
TV-monitor screen and to adjust focus. It also houses a
video pre-amplifier to increase the sensitivity of the IVS at
low light conditions.
The CCD optic module is available in two versions for PAL
or NTSC.
Note: It is necessary to keep the combination of CCD
optic module and inserter/antiflicker module
together as delivered. Mixing the modules might
lead to reduced image quality.
General Description

15
3.2.4 Inserter/Antiflicker Module
The compact inserter/antiflicker module, which is mounted
on top of the ARRIFLEX 535B’s electronic cover, holds the
video camera electronic, an anti flicker processor and the
entire inserter. All electronic control elements, as well as
all in- and outputs are located here.
The inserter/antiflicker module is available in two versions
for PAL or NTSC.
Note: It is necessary to keep the combination of CCD
optic module and inserter/antiflicker module
together as delivered. Mixing the modules might
lead to reduced image quality.
3.2.5 RS cable
The RS cable supplies the IVS with power and information
regarding the camera speed and shutter mirror position.
It plugs into the ARRIFLEX 535B RS connector and the
inserter/antiflicker module. Please observe the color coding.
3.2.6 Data cable ZV4
Note: Sending data to the film camera through the
IVS is only possible when the IVS is switched on.
The data cable ZV4 is necessary to send additional
information such as time code and RS 232 data to the
IVS. This cable is necessary if time code is in use or if
accessories such as the Laptop Camera Controller need
access to the data interface of the IVS and the camera.
If neither time code is used nor data is sent via the serial
interface, it is possible to work without the data cable ZV4.
